1. Market Insight: Global PV-Storage-Charging Ecosystem
Accelerated global energy transition and booming EV infrastructure deployment continue to drive rapid growth in distributed PV, energy storage and EV charging markets. With the worldwide market scale expected to exceed USD 230 billion in 2026, renewable energy assets are becoming mainstream in commercial, industrial, communication and public infrastructure scenarios across Europe, America and Africa.
As distributed renewable penetration rises, grid compliance risks, unregulated power reverse flow, fragmented energy data, and insufficient system compatibility have become critical challenges for EPC contractors, charger manufacturers, telecom operators and global real estate owners. Professional, customizable and grid-compliant monitoring and protection solutions are increasingly essential for sustainable renewable operation.
2. Solution Overview: Intelligent & Grid-Safe Energy Management System
Acrel provides a full-stack renewable energy monitoring and protection solution covering hardware sensing, edge transmission and cloud-based energy management. Built with mature anti-reflux control logic, the system enables real-time visibility, precise regulation and reliable grid protection for hybrid PV-storage-charger systems.
2.1 System Architecture
-
Perception Layer: High-precision AC/DC energy meters, Hall sensors and split-core transformers support full-cycle power data collection for PV arrays, energy storage systems and EV charging terminals.
-
Transmission Layer: Multi-protocol gateways support 4G, Ethernet and LoRa communication, enabling seamless third-party platform integration.
-
Cloud Platform Layer: Acrel IoT EMS Cloud delivers centralized data analytics, real-time alarming, remote O&M, load optimization and automated energy reporting.
2.2 Core Technology: Intelligent Anti-Reverse Current Control
Our proprietary closed-loop anti-reflux strategy ensures fully grid-compliant operation through real-time power detection, dynamic power adjustment, emergency trip protection and automatic grid reconnection. It effectively eliminates reverse power feeding risks, avoids grid penalties, maximizes local green energy consumption, and minimizes abandoned PV generation — a core technical advantage for global distributed renewable projects.
